pm_distUnif::getUnifRandStateSize Interface Reference

Generate and return the size of the seed vector of the Fortran default random number generator (RNG). More...

Detailed Description

Generate and return the size of the seed vector of the Fortran default random number generator (RNG).

The functionality of this generic interface is equivalent to random_seed(size = size).

Returns

seedSize : The output scalar of type integer of default kind IK containing the size of the default Fortran RNG seed vector.

Possible calling interfaces ⛓

use pm_kind, only: IK
use pm_distUnif, only: getUnifRandStateSize
integer(IK) :: seedSize
 
seedSize = getUnifRandStateSize()

Remarks

The procedures under discussion are impure.

Example usage ⛓

program example
 
    use pm_kind, only: SK, IK, LK
    use pm_io, only: display_type
    use pm_distUnif, only: getUnifRandStateSize
 
    implicit none
 
    type(display_type) :: disp
 
    disp = display_type(file = "main.out.F90")
 
    call disp%skip()
    call disp%show("!%%%%%%%%%%%%%%%%%%%%%%%")
    call disp%show("! Get the RNG seed size.")
    call disp%show("!%%%%%%%%%%%%%%%%%%%%%%%")
    call disp%skip()
 
    call disp%skip()
    call disp%show("getUnifRandStateSize()")
    call disp%show( getUnifRandStateSize() )
    call disp%skip()
 
end program example

rm main.exe
gfortran -cpp -ffree-line-length-none -O3 -Wl,-rpath,../../../lib -I../../../inc main.F90 ../../../lib/libparamonte* -o main.exe
./main.exe

Example output ⛓
